The southernmost turbine is out of service and needs repairs, according to University of North Texas spokeswoman Leigh Anne Gullett.
The turbine requires a repair beyond the expertise of anyone on the staff, so UNT in the process of contracting for the work.
The turbines were built alongside the stadium in 2011. They were designed to feed into a separate electric grid that includes the stadium, the Mean Green Athletic Center, other athletic venues and Victory Hall.
At the time, the turbines were expected to generate half a million kilowatt-hours of electricity a year annually, or about 8 percent of what the Eagle Point campus uses in a year.
The move helped the stadium construction project achieve "platinum" status from the U.S. Green Energy Building Council.
